EGG-STAMPING rvmcnmn.

Application filed May 18,

This invention relates to stamping machines and particularly to egg stamping machines.

The primary object of the invention resides in a device by which eggs may be stamped as to the date on which they were laid, so that a buyer may readily determine whether or not the same are fresh.

Another object of theinvention is to pro-' vide a rotatable wheel having a yieldable band removably mounted thereon and which band has its periphery provided with a series of stamps indicative of the days of a month, the selected indicia adapted to be brought into a position to be supplied with ink by an inking pad, and against which indicia the eggs are placed to place an imprint upon the shell of each egg. The band contains all the days of a given month, and is, removable to permit of the interchanging of the same to suit the time of stamping.

Another object of the invention is the provision of an egg stamping machine which also included an egg candler by which the condition of the egg maybe determined before marking, and counters mounted adjacent the stamp wheel by Which a record of the good and bad eggs may be kept.

Nith these and other objects in View, the invention resides in certain novel construction and combination andarrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which r 1 y Figure 1 is'a side elevational view of my improved egg stamping machine. I

Figure 2 is an end elevation of the same partly in section.

Figure 3 is a detail vertical sectional View on the line 33 of Figure 2.

Figure 4 is a vertical sectional view'on the line 14 of Figure 2. v

Figure 5 is an'enlarged vertical sectional view showing the manner of marking an egg ' Referring more particularly 'to the drawings, the reference numeral 10 designates my improved stamping machine in its entirety, and which includes a base 11 from which a standard or support 12 rises centrally therefrom. The top of the standard supports a head 13, to the opposite side of which brackets 14 are removably attached by'screws rial. ed upon the rim and is held thereon by an 1927. Serial No. 192,420.

or the like fastening elements 15. The brackets extend upward from the head in even spaced relation and serve as a bearing for a shaft 16. Fixed or keyed to the shaft midway between its ends is a wheel 17 having a rim 18 extending about the periphery thereof. Fitting over the rim is an annular tubular band 19 which is substantially rectangular in cross section to provide a relatively flat outer surfaceand which is constructed of rubber or other yieldable mate- The tubular band is removably mountannular ring 20, bolted to the rim as at 21.

The tubular band 19 has its outer surface provided with stamp indicia 22 such as type and which is-indicative of the days of a month, the same being consecutively arranged thereon. However, if the name of the egg dealer is desired printed on the eggs,

the same may be embodied in each stamp with the date. The device will include twelve bands for the respective months of a year, and each containing stamps having the respective days of the month thereon. The band is removably mounted on the wheel to facilitate the interchanging of the same when necessary. I For the purpose of supplying ink to th selected stamp, I provide an inking device 22 which comprises a shaft 23 journalled in the top of the brackets 14: in vertical alignment with the shaft 16, and to which a tubular sleeve "24 is fixed. An arm 25 extends from the sleeve 24: and has a head 26 at the outer free end thereof. The head 26 is provided with a recess 27 into which a felt pad 28 extends. The top of the recess is'closed by a swinging cap 29 held closed by a catch 30. For the purpose of supply ing ink to the pad,'the cap 29 is lifted and the ink pouredinto the recess 27 and which is absorbed by the pad.

For properly positioning the selected stamp indicia with respect to the path of movement .of the inking pad, 'I provide a gauge 31 which extends inwardly from one of the brackets and with which the selected indicia isadapted to be brought into register.

For the purposeof actuating the inking device 22, I provide a. lever 32 on one end of the shaft 23 and 'which lever is normally held in a raised position by a weighted arm 33. A hand actuated lever 34 is pivoted to one of the brackets lei. and is connected with the lever 32 by a cable or chain 35 which passes over a pulley 36. Should it be more convenient for the operator to actuate the stamping device by foot, I also provide a foot actuated lever 37, pivot-ed to the base 11, and which has connection with the hand lever 34 by a flexible cable or chain 38. It will be seen that by pressing down upon either of the levers 34 or 37, the ink pad 28 will swing down into contact with the selected stamp or indicia to ink the same prior to the application of the egg to be stamped.

For the purpose of locking the wheel against rotation after the selected stamp has been brought into position, I mount a rotatable wheel 39 on the shaft 16 with which a weighted pawl 40 engages, For setting the wheel, the pawl is manually disengaged from the ratchet which allows tree rotation thereof.

For candling the eggs prior to applying the date stamp thereto, I employ a conventional form of egg :andler 41 which is mounted on one of the brackets 14-. An egg may beplaced against the same and its contents examined as to its condition. if the candled egg is good, a record of the same is kept upon one of a pair of counter wheels 42 which are rotatable with respect to the shaft 16, but journalled thereon. A record of bad eggs is kept on the other of the counter wheels. The periphery of the wheels are provided with consecutive numerals and are rotated to bring the total amount recorded into register with windows or gauges 43.

To cause an impression to be applied to the egg to be stamped an operator presses theegg against the outer surface of the tubular band 19 having the selected indicia thereon, thus causing the band to flex inwardly as shown in Figure 5 of the drawings to conform to the contour of the egg and to relieve the pressure against the egg which might tend to crack the shell of the same. It will be understood that the wheel is retated each day to bring the next date stamp ing from the spirit, of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims hat is claimed as new is 1. An egg marking device comprising a supporting structure, a wheel rotatably supported by said structure, a yieldable tubular band mounted on the periphery of said wheel and having stamp indicia arranged therearound, an ink pad swingingly mounted above saidwheel, means for normally holding said ink pad in a raised position, and manually actuated means for moving said ink pad into contact with the selected stamp indicia to apply ink thereto.

52. An egg marking device comprising a supporting structure, a wheel rot-atably supported by said structure, a yieldable tubular band mounted on the periphery of said wheel and having stamp indicia arranged therearound, an ink pad swingingly mounted above said wheel, means for normally holding said ink pad in a raised position, means for positioning the selected stamp indicia in the path of swinging movement of said inkling pad, and manually actuated means for moving salt. ink pad into contact with the said selected stamp indicia to apply ink thereto.

n. An egg marking device comprising a supporting structure, a shaft journalled therein, a wheel fixed to said shaft, a yield-' supporting structure, a shaft journalled therein, a wheel fixed to said shaft, a resilient member removably mounted on tl e periphery of said wheel, stamp indicia arranged on the outer surface of said member, an ink pad swingingly mounted adjacent said wheel, means for locking said wheel against rotation after the selected indicia has been aligned, and manually actuated means'for moving said ink pad onto the selected stamp indicia.

In testimony whereof signature.
